               -------------- Activity Log --------------
1st Half Observing Specialist: K.A.Gloria
	The telescope was opened at 17:15 MST under high clouds.  Kevin
Krisciunas and I observed for UW02.  Unfortunately the sky wasn't very
photometric.
	Gene Magnier observed for UW14 with DIS.  This was a good night for
spectroscopy of relatively bright objects. No problems to report.  I
continue to log pointing data.
2nd Half Observing Specialist: N.C.Hastings
	No problems at startup. The seeing was quite good for a bit, then
returned to the 1.3" more characteristic of the night. Things went
smoothly until dawn...As of 06:00 the net was still up although we
heard that it would be down beyond NMSU.
